Let verify first to narrow down to where the problem can be. First, make sure the MUTE function is not activated, then check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks (Red and White) to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

    I have the same tv and it was hooked up to a surround sound system and worked fine for 2 years then I started getting a loud squealing during normal sound levels. Eventually no sound at all except for the squeealing. I have used it as a monitor but would like to return it to a television state. What is the diagnosis and cost of the part in question ? I have turn the tv speakers on and the mute is off.....still only squeals.
    please advise

    It seems to have sound processor problem since you are getting the squealing through the audio line out to your stereo system. It will need to have the main board repalced. You can check out www.shopjimmy.com

Akai tv picture no sound


If picture is OK, sound should be there. Check the settings to sound first, ie, 'system' 'mute' etc, by entering the sound menu. If an improper system is selected, the sound will be either absent or distorted. If all the other settings are OK, and still there is no sound, you have to check the audio output section circuit, speakers etc?
